Abstract: In wireless sensor network clustering algorithms, the responsibility of the collection, integration and transmission of data falls on the cluster head, which affects the entire cluster performance. The rapid consumption of the energy cluster heads destroys the network node energy balance. For all the defaults mentioned above, this paper presents a load-balancing clustering algorithm, and under the help of cluster members and assistant cluster head, the cluster head will finish the task. In cluster head selection phase, the number of cluster heads will be controlled by screening twice to determine the cluster head; using ant colony algorithm to find the shortest path to traverse the cluster, the collection of data is done to reduce the pressure of the energy consumption of cluster head. In the process of passing data to sink node, an assistant cluster head will be selected to assist the work of the cluster head. Simulation results show that the algorithm can effectively balance the energy consumption of nodes, and improve the network life cycle.
